A Boeing 747 "Jumbo Jet" has a length of 59.7 m. The runway on which the plane lands intersects another runway. The width of the
tia_tia [17]

Answer:

t = 1.48 s

Explanation:

As we know that length of the Boeing plane is

L = 59.7 m

width of the intersection is given as

w = 25.0 m

now we know that deceleration of the plane is given as

a = -5.4 m/s^2

Also the final speed of the plane while it clears the intersection is given as

v_f = 53 m/s

now we have

d = (\frac{v_f + v_i}{2}) t

(25 + 59.7) = (\frac{53 + v_i}{2}) t

also we know that

v_f - v_i = at

53 - v_i = -5.4 t

now we have

84.7 = (\frac{53 + 53 + 5.4t}{2})t

by solving above equation we have

t = 1.48 s

Charge q is 1 unit of distance away from the source charge S. Charge p is four times further away. The force exerted between S a
zhenek [66]

The correct answer is:

sixteen times


In fact, the distance between charge q and the source S is 1 unit. Instead, the distance between charge p and the source S is 4 units. The magnitude of the electrostatic force is inversely proportional to the square of the distance between the charge and the source:

E \sim \frac{1}{r^2}

where r is the distance. If we take the force between q and S as reference, we have r=1, so that

E_{qS}=\frac{1}{1^2}=1

while the force between p and S is

E_{pS}=\frac{1}{4^2}=\frac{1}{16}

Therefore, we see that the force exerted between q and S is 16 times the force exerted between p and S.
